T0 aZZwhof/n t may concern Be it known that l, JOHN El. Lyons, e citizen of ,the United Sta-tes, residing at vZVilkeS-Berre, in the county of Luzerne and State of Pennsylvanie., have invented e new and useful Automobile-Tire nml Rini', of

'which the following e specification.

This invention relates to improvements in vehicle tires and rims for the receptionv is to and around which is placed 'a casing or.

covering and which is engageclby the rim and so lielcl. in place.

A. further object is to provide n tire, the

bocly portion oi' which is' 'formed of Wire,

the Wire being bent substantially.-fici-rouler" throughout n 'ijorMnro/"iil is bent ont- Wertlly'corni diverging arms :iK-,the in- -"'ner peripheral portion of the loolfof the i flattened somewhat to 'illus Wire so that encli spring loop is engaged oy the converging sides oi.t the wheel rim and held in place thereby.

A furtlier object is to provide n. tire the body portion of '.i cli is formed ci Wire Wound in the 'form of coils :unlv with the :mejor portion of each coil 'formed lsubstantinlly circular throughout n nnijor arc :incl with the top of the sniclcircnlnr portion incresse the bearing snrfaoeoi' tlie Another object is to provide fi Wheel with .f1 clenclier rini and to which tire Wliioli depends on n helical or continuously coiled spring for its resiliency, the successive convolntions boing' provided et their base with di'vergino; portions engage able oy the converging clenclier rim und to provide n casing surrounding zin secured to the spring' coil und to one side of said casing is secured a continuous ring mail to tlie opposite side, is scoured n, sectional ring ootli of Wliicli :ire adopted to engage tlie olencner rims.

the preferable embodiment of my invention is illustrated in which;-

cross senion extending substantially parallel 'all of Wliicli cloni-ly illustrated in Fig. 5l

of tlie drawings.

The tire isnin up of o. vcontirnous coil ofY wire l0 snlistnntinllj. olronlzir throughout tlie mejor portion of circle unil preferably straightened at its upper extremity for a short distance` as -illustrated in Fig. 4 so that the tirewill be 'Oiven the proper transverse contour and similar to tires now in use. Each convolution of the wire coil is 'provided at what is termed its base with the will be held to .the clencher rim by reason of the fact that the base portions of theconvolutions fit within and arel embraced therebetween, the samegbeing substantially as illustrated in Fig. 3 of the drawin' c.

Extending around the wire coil 10 1s the casing 13 formed of fabric or other suitable material and to the lower extremitiesA of which fabric are secured the clencher-rin s 14 and 15. The ring 14 as illustratedm' Fig. 1 is a unitary structure and is riveted or otherwise held to the casing 13. The ring lillustr'ated in Fig. 2 is formed of a plurality of sections so that the casing may be drawn over or detached from the wire coil. In order that the rings will properly engage the clencher rims 8, the saidv rings are provided with the upturned edges 16 which are adapted to interlock or interen- 1 gage with'the bent portions 9 of the clencher rims.

Rivetedlysecred to the covering' or casing 13 is the tread 17, the same being rendeied antiskidding b'y the rivet heads 18 which project therethrough. The lugs or rivets extend 4through the casing vand are interposed between the adjacent vconvolutions of the spring'coil v,which prevents the .shoe or casing from shifting relative to the coil and vice versa, the coil shiftingI relative to the shoe. The tire herein described may` be easily removed or readily attached to the clencher rim by loosening the bolts 7 and drawing the clencher flanges apart which y allows for the disengagement of the rings therefrom after which the sectional ring 15 is first disengaged and the` covering and tread is drawn back 0H' 4of the spring coil after which the continuous ring 14 mayv also be removed. kThe spring coil may then be released from the clencher rims and av The providing of each convolution of the spring coilwith the diverging arms 11 andA base member 12 extending therebetween adds certain resiliency to the entire coil as. the ends ofv the circular portion 20. of the convolution may .shift by bending of the arms 11. y

Briefly considered, the tire herein disclosed embodies a helical tread spring, each y convolution of which comprises a resilient tread loop,4 straight, l laterally,k diverging arms 11 and a straight, continuous, intensible cross bar 12 connecting the arms. The

lto`; the fact that the arms 11 are straight,

the base 6 along two diverging lines indicated by the arrows A in Fig. 3.' Owing to the fact that the pressure is applied in the direction of the arrows tend to separate inthe direction of theaithe side arms 11 rows B. This tendency of the arms 11th separate in the direction of the arrows B is resisted'not only by the wings 8 of the base 6, but by the cross bar 12 as well. observed that the cross .bar l2v is straight, andy will remain at a fixed' length, thereby to coperate with the wings 8 in resisting a separation of the arms 11 in the direction of the arrows B. So far as I am advised as to the 4'state of the art, the straight, convergingarms 11, in combination with the straightlcross bar 12, the base 6 and the wingsv 8 embrace novel and patentable features.l If the arms 11 stood at right angles to the cross bar.v 12, the force applied lon gitudinally of the arms 11 would have no component parallel to the'cross bar 12 and 1n the direction of the arrows B. i If the bar 'constructed otherwise than in the straight form shown, the arms 11 would tend to bend, and, when the tire was compressed, the

.lateral pressure in the direction of the arrows B would not be transmitted into the arrows A.n The combination. embodying the parts and features above specified operates in a novel' manner and produces new results.

Having thus fully described my invention, what I claim is:-

In a'tire. a helical tread spring each convolution of which is disposed transversely of the axis of the tire and embodies a resilient tread loop. straight` laterally diverging arms, and a continuous, inextensible cross bar connecting the arms; and a base on It is to be which the cross bar rests, the base comprising wings which bear upon the outer faces ofthe arms, the straight formation of the arms tending toprevent a transverse fieX`- ure of the arms intermediate their ends and serving to transmit lateral pressure to the base in straight diverging lines when the loop is. compressed, the cross bar being straight from end to end whereby when the v 105 base along straight lines represented by the .lq0`iscompressed, the dross bar will remain as my own, I have hereto affixed my signa-- at "a fixed length and will co'perate with ture in the presence of two Witnesses. the Wings in resisting the tendency o the v y zu'ms to separate laterally due to the straight A :JOHN LYONS' 5 divergngyelaton existing between l*the Witnesses: arms.
